Invalid type for SQLite3Result::columnName

Psalm complains when comparing the return value to false. But the method can return false: https://www.php.net/manual/en/sqlite3result.columnname.php

I found these snippets:

https://psalm.dev/r/634c35d072

<?php

function getColumnName(SQLite3Result $result, int $index): string {
    $name = $result->columnName($index);
    
    if ($name === false) {
        throw new \OutOfBoundsException("Invalid index $index.");
    }
    
    return $name;
}

Psalm output (using commit 16b24bd):

ERROR: TypeDoesNotContainType - 6:9 - string does not contain false
